Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or pink in garden varieties), with either uniform or contrasting colored tepals and corona.

Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten parts with approximately 50 species. The true quantity of types has assorted, depending about how they are categorized, as a consequence to similarity between hybridization and species. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the true name Narcissus is undiscovered, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the young ones of that name who fell deeply in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.

The species are indigenous to meadows and woods in southern European countries and North Africa with a center of variety in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be extinct, while some are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred mostly on holland. Narcissi are popular as slash blooms so when ornamental plants in private and general population gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. Like other members of their family, narcissi create a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if accidentally ingested. This property has been exploited for medicinal use within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in fine art and literature, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to fortune, and as icons of planting season. The daffodil is the national rose of Wales and the sign of cancer charities in many countries. The looks of the crazy flowers in spring is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage bulb. They regrow in the following yr from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as high as 80 cm.

The plants are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, thin, strap-shaped leaves arise from the light. The vegetable stem bears a solitary bloom, but once in a while a cluster of blossoms (umbel). The blooms, which are conspicuous and white or yellowish usually, both or almost never renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The plants may suspend down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berries includes a dried out capsule that splits (dehisces) liberating numerous black seeds.

The bulb lies dormant after the leaves and blossom stem die back and has contractile roots that yank it down further in to the soil. The flower stem and leaves form in the light, to emerge the next season. Most types are dormant from summer months to later winter, flowering in the spring, though a few kinds are autumn flowering.
